Cheers for the replies I tried different HDMI and still gett the the same
Tried the power off and got nothing
My backlights are working just not getting a picture, typical I got an Xbox series x yesterday and today it dies
Have you tried factory resetting it ?
And this
Change Picture mode and backlight settings
If you’re able to get the picture after following the above fix, then changing picture mode and backlight settings can help you in fixing the black screen of death issue on your LG tv. You need to make the following changes in your picture and backlight settings.
Go to settings then select all settings.
Now select the picture from the list.
Select picture mode settings.
Now set the picture mode as standard.
Now decrease the backlight and set it at the lowest between 10-30.
Set the brightness at 50.
These changes will prevent your smart tv backlight from overheating and you’ll not face an LG tv black screen issue on your LG smart tv.
